Dry Dams in the Desert: Chasing Land Subsidence and Earth Fissures with Geophysics
Homogenous embankment dam flood retention structures (FRSs) were built throughout central Arizona desert basins in the mid-twentieth century to protect mostly agricultural lands and military installations...
Difficult-Access Rockfall Mitigation: Design and Construction Way Up High!
Rockfall mitigation projects frequently require work at elevated positions. This is not something that comes naturally for many engineers and geologists. Palms sweat, knees knock, and voices may start...
Cracking the Nuclear Code: Finding an Alternative to the Nuclear Density Gauge
Two of the most basic quality control tests made in the field during soil construction are the soil’s moisture content and density. The establishment of a uniform procedure to compare the performance of...
A Sinking Feeling in Happy Valley: Limited Mobility Grouting Arrests Movement of Emergency Room
Shortly after construction began on a new emergency room addition at the Mount Nittany Medical Center in State College, PA (a.k.a. "Happy Valley"), the existing structure and new construction began to...
Advanced Fracture Control Procedures for Deepwater Platforms and Compliant Towers
This paper describes an integrated approach to fracture control problems – applied first as a necessary adjunct to the authors' own engineering practice, then in developing...
Offshore Platform Steel Specification
The discovery in the 1980's of local brittle zones (LBZ's) in and near the heat-affected zone (HAZ) of the fabrication welds in certain offshore platform steels...
Detection of Fatigue Cracks in Structural Members
CO2 Sequestration: Fractures are Enabling Clean Energy Options
Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...
Nonlocal Integral Formulations of Plasticity and Damage: Survey of Progress
Modeling of the evolution of distributed damage such as microcracking, void formation, and softening frictional slip necessitates strain-softening constitutive models. The nonlocal continuum...
